Explosion-proof thermocouple is introduced in detail1

Abstract: industrial explosion-proof thermocouple is a kind of temperature sensor, a wide application in the chemical industry control system, through the temperature sensor, can control the temperature of the object parameter into electrical signal, passed to the display, record and adjusting device, the system testing, adjusting and control.

industrial explosion-proof thermocouple is a kind of temperature sensor, a wide application in the chemical industry control system, through the temperature sensor, can control the temperature of the object parameter into electrical signal, passed to the display, record and adjusting device, the system testing, adjusting and control. In chemical plant, the production site is often accompanied by various kinds of flammable, explosive chemical gas, steam, if use common thermocouples are not safe, easy to environment caused by gas explosion. On these occasions, therefore, must use explosion-proof thermocouples as temperature sensor, the company production of explosion-proof thermocouple products, suitable for d Ⅱ CT6 range temperature classes is the explosive gases in dangerous places.

2: the characteristics of various forms explosion-proof, explosion-proof performance is good. Low pressure reed temperature sensing element, ant-vibration performance is good. When measuring range is large; Low mechanical strength, high pressure good performance. 3: temperature measurement range and tolerance
